BACKGROUND OF INVENTION CLASSIFICATION, DEFINITIONS TECHNICAL FIELD

This is to state that my invention, Magnum Bullet Darts, pertain to the field of endeavor, which is known as amusement devices and games. The U.S. Patent Manual Classification Number is 273 and 463. Technical Field.

The bullet darts with standard shafts are unique by design. The dart owner can remove the shaft, and insert lead shot into cartridge, through the shaft opening hole, for desired weight of dart.

My 357 Magnum Dart with self-contained, sliding adjustable shafts solves the problem of needing to change the shafts for the throwers desired lengths. This state of technology adds convenience as well as saving money for the dart owner. My darts stand above any description of prior art.

BRIEF SUMMARY OF INVENTION

The general idea of my dart concept is to add a new type dart into the dart thrower's world, a superior, attractive, and unique type of dart, that is more convenient and economical to use.

The advantages of the bullet darts with the standard shafts, is that, after the removal of shaft, the dart owner can add weight to the dart by inserting lead shot inside the bullet cartridge through the shaft hole, “at the bottom of the cartridge” for the thrower's desired weight or comfort.

The advantages of my 357 Magnum Self-Contained Sliding Adjustable Shaft Dart is this; they do not require the dart owner to purchase different lengths of shafts for their throwing comfort.

DETAILED DESCRIPTION OF INVENTION

Magnum Bullet Darts are a new and unique type of throwing darts. They are constructed from actual fire-arm cartrige components of all types and size. Automatic, semi-auto, small to large calibers, magnum to regular types. Magnum Bullet Dart is the only dart that has self-contained sliding adjustable shaft for the owner's convenience and comfort of desired lengths. This makes the dart more economical to use.

DESCRIPTION OF THE PREFERRED EMBODIMENT

FIGS. 1 and 2 of drawing sheet, depicts a 30 Caliber Bullet Dart that's complete with standard shaft applications and is number 10.

Process of Construction and Assembly of Components and Composition

Starting with a new 30 Caliber Cartridge No. 12. At the back, No. 14, drill out primer hole and tap, threads No. 16, for the standard shaft application No. 26. Screw shaft threads No. 27 into the threaded primer hole No. 16. This completes the back of dart.

Take a new 30 caliber bullet, that is full metal jacketed No. 18, insert bullet No. 18 into new cartridge of No. 12 at the front opening of cartridge No. 22.

At the front of bullet No. 18 at center, drill a 1/16 of an inch hole No. 19, ¼ of an inch deep, into bullet. Take No. 20, a 1/16 of an inch spring steel rod, 1 1/2 inch long, and super glue it into place No. 19. Sharpen end of rod No. 20 and dart is complete.

FIGS. 3 and 4 of drawing sheet depicts the 357 Magnum Bullet Darts complete with the self-contained sliding adjustable shaft application, and is numbered 10.

Process of construction and assembly of components and composition.

Starting with a new 357 Magnum cartridge No. 12, “brass or nickel,” at the back No. 14, drill out the primer hole No. 16, with a ¼ of an inch drill bit.

Shaft construction and components. Start with a plastic tube for the shaft No. 26. It has ¼ of an inch outside diameter and an ⅛ of an inch inside diameter No. 27. With a length of 1⅝ of an inch. Acquire a solid plastic plug, 3/16 of an inch thick No. 29, drill an ⅛ of an inch hole in the center of the plug No. 29. Using a countersunk drill bit, bevel the hole drilled in plastic plug No. 29. The beveling is No. 30. Using a 5/8 inch of an inch long with a 5/32 of an inch threaded, bevel headed screw No. 31. Attach plastic plug No. 29, to plastic tube No. 26, with screw No. 31. Now, slide completed shaft No. 26, with plug No. 29 inside cartridge. Push the end of the shaft tube No. 26, through drilled hole No. 16, until the back of the plug No. 29 rests at the bottom of the inside of the cartridge No. 24. Insert No. 31 of flight top holder No. 32 into No. 28, at the end of the shaft No. 26. Shaft is now complete and in place inside cartridge No. 12.

Take a new 357 Magnum full metal jacketed bullet No. 18, insert bullet No. 18 into new cartridge No. 12 at the front opening of cartridge No. 22.
